The Telephone Patent Conspiracy of 1876 is a good introduction to understanding science and society at the time Thomas Alva Edison, Alexander Graham Bell and a lot of their contemporary inventors, engineers and scientists changed the world by introducing electric lighting and telecommunicatins to the homes and offices.
The book may appear somewhat biased against Bell and focus mainly on the battle between Bell and Gray. People like Emile Berliner and Edison get only cursory treatment, and Antonio meucci is hardly mentioned. At times the author treats information from newspaper clippings with the same authority as official records. Readers are adviced to check the footnotes.
Still, the book is recommended reading for anyone interested in the history of technology.

However, I am appalled at the typos and editing of this book. In the introduction alone there are many mistakes: misuses of "it's" and "comprise" and several spelling and grammar mistakes. These continue throughout the book in varying degrees. (The chapters, I think, were written by different authors, but the styles were not unified, so quality varies.) In addition, the figures lack a consistent format and are clearly borrowed from other publications, with bad effect. In several cases, the figures are black and white copies of color originals, and the loss of detail is nearly complete. It is not apparent whether any original figures were developed for this book.
Some of content is conspicuously absent, too. For example, I was hoping to find a well written explanation of the different types of Stirling engines, and on the web, I have found many refences to alpha, beta, gamma, and delta types. While different engine types are explained, this naming scheme is not covered.
In general, I would not reccommend this book because of the sloppy editing and nearly useless figures. While it does present a good amount of material, there are some absences and the ever present typos making reading it a chore.

However, I have to give a higher rating than just 2 stars. The book gives a very balanced review of the then current state of Stirling development, and gives clearheaded predictions as to what applications may develop, and what technical improvements are needed.
I particularly liked the section that dealt with the advantages and disadvantages of Stirling machines vs other alternatives. That section is of vital importance to people who would like to do something with stirling engines because it points out where to find the tiger in the grass, waiting to devour the unsuspecting hobbyist/engine builder.
It is not a book with much if any math or analysis, or detailed design information.

An interesting read, but certainly not something that I will lose sleep over.
